PRESS FOR MAKING VENEER DOORS, 84,6.

SPECIFICATION forming part of Letters Patent No. 585,906, dated July 6, 1897.

Application filed October 22, 1896.

To all whom, it may concern:

Be it known that I, JOHN S. CARTER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Presses for Making Veneer Doors, &c.; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improvement in presses for making veneer doors, the. and it consists in the novel features of construction and combination of parts hereinafter described, reference being had to the accompanying drawings, which illustrate one form in which I have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure 1 represents a top plan view of my improved press. Fig. 2 is a side elevation of the same. Fig. 3 is an end view. Fig. 4 is a vertical transverse sectional view. Figs. 5, 6, 7, and 8 are detail views of parts of the mechanism.

The object of my invention is to provide a simple and efiective press for making veneer doors, in which the door can be built up, the parts glued together and subjected to compression horizontally and vertically to unite them, and one which can be operated for this purpose without the employment of skilled labor.

In the drawings, Arepresents the horizontal bed-plate supported by suitable standards a a at a convenient height and having its top face provided with a series of parallel longitudinally-extending dovetail grooves 00' a, four being shown. The bed-plate is also provided at each side with a series of parallel transversely-extendin g dovetail grooves a of.

B B represent adjustable sliding blocks adapted to fit the grooves a, each block being provided with a guide-plate b, slotted and secured to the block by an adj usting-screw b, which extends vertically through the block and engages the bottom of the slot a to clamp the block in the groove and the slotted plate to said block. I may, however, provide the block B with screws 12 17 as shown, for clamping the block in the groove, in which case $eria1 No. 609,671. (No model.)

the screw b will serve simply to adjust the plate I) with respect to the block. These guide-plates and blocks can be placed. in any of said grooves a, and will be arranged to serve as guides in placing the parts. of the side frames of the veneer door which is to be built up in the press in position. They will obviously be adjusted to different positions, according to the style of the door which is to be constructed.

0 O represent the lateral clamping-bars, each consisting of a longitudinal bar having on-its innerside avertically-extending flange to engage the edge of the door. The bar O is provided with a dovetailed block 0 for each of the grooves a a formed integrally therewith or secured thereto, as in the drawings, and I provide each bar with two or more (in this instance. three) devices for moving it laterally. In the present case each of these actuating devices consists of an eccentric or cam D, secured to the bed-plate by means of a bolt d, which passes through a transverselydisposed slot a in the bed-plate, and is provided either above or below the bed-plate with a clamping wing-nut (1. (See Fig. 8.)

01 represents an eccentric-strap which is connected to the clamping-bar O, and the eccentric D is provided with an arm d by which it can be turned. In order to secure the simultaneous movement of all the actuating devices for each clamping-bar, I provide a longitudinallyextending actuating-rod E, to which each of the arms 01 is pivotally connected, so that the longitudinal movement of said rod E will move all the eccentrics Dand insure the even movement of the entire clamping-bar C. At one end of the bed-plate is a vertically-disposed plate F, having a horizontal slot f therein, through which extends a threaded portion cof the actuating-rod E, said threaded portion being provided with a nut 6, preferably in the form of a hand-wheel, by means of which said rod can be moved endwise to move up the bar 0. One of said rods E is also provided with jam-nuts 6 (see Fig. 1,) by means of which the position of its bar 0 can be regulated so as to form a solid resistance against which the other bar clamps the door.

It will be noted that by loosening the wingnuts d the eccentrics, bar, and rod E can be simultaneously moved transversely of the bed-plate to adjust it to any width of door which it is desired to make.

At each end of the bed-plate I provide an end clamping-bar G. This bar may slide upon the top of the bed-plate or it may be provided with dovetail guiding-blocks engaging slots a a, but it is ordinarily suflicient to allow it to slide upon the top of the platen, as shown. Each of the bars Gr is provided with a single actuating device consisting of the eccentric D, having the securingbolt passing through a longitudinal slot at in the platen and provided with wing-nut d, the strap 01 and an operating-arm d, which is long enough to be grasped and moved by the operator. It will thus be seen that by means of the clamping-bars O O and G G the pressure can be applied horizontally in both directions to the door.

In order to apply pressure vertically, I employ a series of transversely-extending presser-bars II. These bars are preferably formed of U-shaped castings having a fiat lower face, thus combining strength and minimum weight, and at the rear side of the bedplate they are each provided with a horizontal hinge-bolt h, which is engaged by an eye bolt h, extending down through a slotted portion A of the bed-plate,whi ch in this instance consists of a slotted bar bolted or otherwise secured to the side of the bed-plate. The eyebolt h is provided with a nut above and below the bar A, so that the height of the presser-bar can be accurately adjusted. In order to apply the pressure just where it is most desired, I provide each bar II with a series of presser-blocks I, which are preferably formed of wood or iron, covered on their lower sides with a heavy rubber facing 1'. Each of these presser-blocks is provided with a pair of attaching-bolts t" i, extending up to the top of the bar H and through a cross-plate 11 where they are provided with wing or other nuts, so that they can be placed in any desired positions along the bar II. It will also be seen that the presser-bars may be moved longitudinally of the bed-plate to any desired position by loosening the nuts on the eyebolt.

At the front side of the bed-plate is a bar A (formed in this instance separate from and secured to the bed-plate,) provided with a dovetail slot a and in this slot I locate a number of sliding blocks K, which carry the for clamping it in the slot 0. and with a pair of perforated ears 70 70, forming bearings, in which is journaled an eccentric or cam shaft W. This shaft is provided with an operatingshaft are placed the ends of a loop or yoke K. The front end of each of the presser-bars is provided with a shoulder 7L2, which is engaged by the yoke K, after which the eccentricshaft is rotated to apply pressure to the presser-bar.

The blocks K will of course be adjusted along the slot or groove a, so as to be in line with the presser-bars. In order to sustain the presser-bars when not in use, I provide each with a rope L, passing over a pulley Z in a suitable support and provided with a weight L, by which means they may be maintained in an elevated position above the bed-plate.

The operation of the press is as follows: The device having been adjusted to the particular size and style of door to be made, the parts of the door, consisting of thin strips which have been made to iit accurately with respect to each other, are laid in position and glued. One of the side clamping-bars and the en d clamping-bars are then moved up by their actuating devices in order to apply pressure to the edges of the door. The presser-bars H are then drawn down upon the door. The yokes K are slipped on and the pressure applied, as previously described. When the door has set long enough, the pressure devices are released and the finished door is re moved from the press.

In order to adapt the press to doors of dif ferent thickness, the yokes K are each provided with a set-screw 70 which engages the bottoms of the cross-bars H when a thin door is being made, and can be set to any desired position by means of jam-nuts k k These set-screws cooperate with the adjustable eyebolts which secure the rear ends of the crossbars to the bed-plate, and by means of these devices the press can be arranged to make doors of different thickness. 7
